The red stripes tell the story . After explaining the science of spheric mood alteration , Jeremy Hoffman brought it home with a boldly colour in infographic : a series of vertical bar , ranging from glum blue to inscrutable Marxist , that show departures from average one-year temperatures in Charlottesville since 1895 . The pileup of red bars to the right hand in the graphical record , mean the last decade or so , confirmed what we ’ve all been feeling . It ’s getting strong in here .
That was just one of many wakeup calls from the Piedmont Master Gardeners ’ 30thanniversary memorialisation at the Paramount Theater on September 8 . Titled “ The Future of Our Landscapes in a change Environment , ” the programme offered insight into what ’s happening to the planet , what it intend to us and to our community , and what we must do now to stave in off harmful impacts in the eld forwards .
Hoffman , main scientist at the Science Museum of Virginia , was part of a roster of grand utterer and panelists our program brought to the stage . It also featured Dennis Dimick , whose 35 years atNational Geographicincluded stretch as a picture taking editor and as surroundings editor .
With stunning range from the powder store ’s pages , he presented a visual journey through a world that now strains to support more than 7.5 billion people . He frame his narrative with the concept of the Anthropocene , or human age , a proposed geologic epoch defined by our transformation of the planet and the mark it will leave in the geological record long after we are gone .
The climate disruption already upon us — extreme temperatures , clayey haste events , develop sea point , coastal flooding , and lengthening growing seasons — are among the effects of this transmutation . They are largely a product of our reliance on fossil fuels that have made our way of sprightliness possible but now place threat to its future .
rev Up the Greenhouse Effect
The second intensity of theFourth National Climate Assessment , release last twelvemonth , spell out the physics of what ’s occurring :
In his presentment at the Paramount , Hoffman noted that French physicist Joseph Fourier greet the glasshouse impression as betimes as the 1820s . By the 1890s , as the Industrial Revolution was strike full stride , scientists were already foretell rises in orbicular temperatures as ember - displace manufacturing plant pumped more carbon copy dioxide into the ambiance . That was only the beginning . Since 1900 , concentration of atmospheric CO2have jumped from under 300 parts per million to 408 parts per million . And the bulk of that increase has pass just since 1960 .
How Climate modification Affects Our arena
We are now seeing the impacts in our region . For example , hardiness zones are creep northward . According to a National Oceanic and Atmospheric Administrationanalysisreported recently by theNew York Times , western Virginia will unite the Piedmont in Zone 7 by 2040 , and Tidewater will move from Zone 7 to Zone 8 . Hoffman referred to astudyby Old Dominion University ’s Michael J. Allen documenting that spring and summertime are starting earlier and autumn and winter are starting subsequently in many urban area around the land . Some of the most marked changes in seasonal kickoff date are occurring in Richmond .
search at data from Charlottesville , Hoffman ’s colorful visualisation made plain that where we subsist is getting hot . He also observe that first freezing dates have suffer later since the 1890s , and last freeze dates have moved up about a calendar week , from April 8 to April 1 . That fathom like good news for gardeners and raiser , butresearchshows that such change have made budding works and early - sprouting craw more vulnerable to late cold ginger snap . So - called “ false springs ” can lead to harvest failures .
Moreover , Charlottesville now has 20 more annual mosquito day than we did in 1980 , and spikes in tree pollen counts are occur earlier in primal Virginia , making allergic reaction seasons longer . As for wildlife , Hoffman noted that the National Audubon Society has projected major changes in the geographical ranges of North American Bronx cheer as the major planet warms . For instance , the wintertime ranges of the common loon and wild turkey will slip out of most of the South by 2080 , and the purple finch is ask to all but vanish from our winter feeders in Virginia by that time . Bees are in trouble as well;scientistshave found that bumblebee are go to align their chain as the climate heats up and could confront decline .
What the Future Holds
According to the Fourth National Climate Assessment , more negative impact are in the offing for Virginia and other southeastern states :
“ interchange wintertime temperature extreme point , wildfire patterns , sea levels , hurricane , flood tide , drouth , and warming sea temperatures are expect to redistribute metal money and greatly modify ecosystems . As a result , the bionomical resources that people depend on for livelihood , tribute , and well - being are increasingly at peril , and succeeding generations can carry to see and interact with lifelike systems that are much unlike than those that we see today . ”
He also points to rising temperature that can result in a bully figure of very red-hot days , with wellness consequences for multitude who work alfresco or who miss access code to atmosphere conditioning . “The sustentation and growth of green quad — urban tree cover , fleeceable infrastructure — can be a utilitarian solution to mitigate these encroachment , if carefully planned with an knotty residential district , ” he said . However , climate modification is also threaten the tree diagram that give us specter . He noted that warmer wintertime may have cannonball along the scatter of the woolly adelgid , the worm that has wiped out most of the California fern canopy in the heap . Likewise , the cattle ranch of the emerald ash borer threatens the cover provided by ash tree Tree .
attempt solution , Globally and Here at place
The National Assessment outlines style our society can resist off the impact of a changing clime , but we must move quick to cut back greenhouse gas discharge and other contributors to the problem . Dimick picture promise in the work ofProject Drawdown , a research brass dedicated to identifying the most viable solutions . It advocates dozens of options , place from transition to wind and solar power to measures such as refrigerating management as uprise temperatures increase global demand for air conditioning and cooling system .
Master Gardener and environmental consultant Frank Reilly , who served as master of ceremony for the Paramount upshot , urged adoption of mood - conscious horticultural drill , such as establish carbon - absorbing trees and shrubs , descale back lawn ( and all that mowing ) , and no - till cultivation that save carbon in the grime . “ Best are practice session where we can both reduce our use of fossil fuel to mitigate climate alteration and do things to help us adapt to climate modification , ” he said after the program . As an exercise , he paint a picture “ planting the correct plant in the right place while pull in that the ripe industrial plant might be change for each of our places . ”
Hoffman emphasise the motive for just communication and greater public date on this issue . He pointed to a climate opinion view showing that 71 percent of Virginians believe global warming is happening , and 78 pct documentation regulating CO2as a pollutant , but only 42 per centum consider ball-shaped thaw will harm them in person , and just 21 percent recall hearing about mood change in the medium every hebdomad .
For our part , the Piedmont Master Gardeners have a new pecker for educating the public about way of life to shorten our environmental footprint . Titled “ Be a Steward of the Environment , ” this guide to sustainable practice and helpful websites was unveil at the Paramount and will be used in PMG ’s outreach in the months ahead . A written matter is let in — in two formats — at the terminal of this article .
As it happens , PMG’s30th day of remembrance event came together at a time when the City of Charlottesville , Albemarle County , and the University of Virginia are each makingnew commitmentsto mood action and are recrudesce or updating their plan and goals . These effort have tolerate fruit in late month : City Council and the Board of Supervisors have both adopteda glasshouse gun reducing target of 45 % by 2030 and have pledged to reach carbon disinterest by 2050 . The University is forrader of docket in pursuing its goal to cut back greenhouse accelerator pedal emissions 25 % below 2009 levels by 2025 . It is alsoin the process of arrange a raw step-down target and developing a fresh sustainability program for 2030 .
As educator and environmental keeper , Master Gardeners have a role to act in helping our community live up to these commitment . Please join us .
